WASHINGTON, D.C. -- The Consumer Product and Safety Commission announced Thursday the recall of 2 gas-fired hot water boilers due to a carbon monoxide hazard.

CPSC tells WFMY News 2 New Yorker Boiler and U.S. Boiler both recalled their products because the air pressure switch can fail to shut down the burners when there is blockage in the vent system. They say this allows the boiler to emit excessive amounts of carbon monoxide and poses a CO poisoning hazard to the consumer.

The recall affects 191 units of the New Yorker boiler and about 26,000 U.S. boilers.

CPSC says no injuries have been reported for either model.

If you bought one of these boilers, CPSC says you should immediately contact the installer or distributor from whom you purchased it to schedule a free in-home safety inspection and repair.

Both models were sold at plumbing and heating wholesale distributors nationwide.
